(GRANTED UNDER THE PROVISIONS OF THE-ACT OF MARCH 3, 1921, 41 STAT. L, 1318.)

To cZZ whom it may concern:

Be it known that I, JOHN Ronnn'r NIL;

LIAMS, subject of the King of Great Britain and Ireland, and resident of Hochdale, in the county of Lancaster, England, have invented certain Improvements in Separators for Ring-Spinning and like Machines, (for which I have made application in Great Britain Feb. 16, 1916, and October 30, 1916, Patents Nos. 2,305 and 15,421, respectively, of 1916,) of which the following is a specification.

. My invention relates to improvements in separators for ring spinning and like machines principally employed in dealing with cotton yarns, the object being to provide simple and cheap improved forms of device of the class which can be placed in operative or inoperative position collectively or individually as may be required.

My invention comprises separator devices for ring spinning and like machines each formed of wire or metal stripand so shaped as to enable them to be sprunginto or out of their pivotal positions as hereinafter fully described and claimed.

My invention will be fully described with reference to the accompanying drawing in which,

Fig. 1 is a side elevation partly in section of one form of separator,

Fig. 2 plan of a plurality of separators,

Figs. 3 and 4 and Figs. 5 and 6 similar views to Figs. 1 and 2 of other forms of separators,

Fig. 7 side elevation of a further form of separator,

Fig. 8 plan of same,

Figs. 9 and 10 similar views to Figs. '7 and 8 of a modification o f-the separator shown in the last named figures,

In all the separate views of the drawing like parts are indicated by the same reference characters.

I employ a rail 4 running longitudinally of the ring spinning or like frame, said rail preferably extending the full length of the frame though it may be divided transversely into two'or more lengths each substantially a duplicate of the others. The rail is adapted to fit in bearings at both ends andat one or more intermediate points so that it may be turned therein about its axis. The rail may be of any suitable cross section. In the drawing it is shown as made of angle iron. It is adjusted about its axis a- (Fig. 2) by one or more set screws Z) passed through a fixed bracket 0 or brackets, so that 1ts upper face may be horizontal or at any suitable angle to the latter. Any other simple mode of adjustment for the purpose named may be employed. The arrangement just described does not by itself constitute a part of my invention.

I11 the arrangement shown in Figs. 1 and 2 the separators (Z. constituting the main feature of my invention are made separately from metal wire looped as shown at the front end and then diverging at the rear end into arms 6 bent at their extreme rear ends into pivots 7 which pass freely into the hookshaped forward ends of cover or bearing plates 9 secured to the rail a by bolts h, screws or the like. Part of each separator immediately in front of its pivotal point rests upon the upper face of the rail or, so that when the latter is adjusted as previously stated the combined separators may be made to assume a horizontal position or an angle to the latter. Or again the rail a may be turned about its pivots to place the separators in or about the operative position stated or in the inoperative position as indicated by the broken lines in Fig. 1. Each separator may be turned to such broken line position individually without turning the rail a. The front portion of each separator contacts with one end of yarn as the latter is passing towards the rear of the space 2" occupied by the bobbin and with the adjacent end of yarn as it is passing to the front of the space as will be well understood by those engaged in spinning. When one separator of the kind which is self contained as regards each end of yarn as hereinafter referred to is turned to operative position the yarn only contacts with the arm at one side. In either case the adjacent ends of yarn are kept separate as they balloon. A rod 7' serves to support the separators when turned to inoperative position. This rod may be adapted to allow of forward movement to throw the separators collectively into operative position if required without turning the rail a about its pivot for that purpose. Said rail a may be operated by a handle such as 73 fixed at each end of it. The weight of each separator keeps it in the operative position. Each separator is sprung into position in the cover plates 9 whilst the latter remain fixed. This enables them to be changed readily if required.

Figs. 3 and 4 indicate a modified form of the arrangement shown in Figs. 1 and 2, the difference mainly lying in the curving of the ends of'each separator and loopingthem vertically so as to present a deeper surface to the yarn as it rotates.

Figs. 5 and 6 show another form of the wire separator which is self-contained as regards each end or yarn. It is made in one piece of wire looped at each side on to present a deep surface vertically, the looped portions being parallel to each other as shown or curved inwardly if required. The rear centre portion a forms a pivot with the cover plate 9, whilst the single rear ends 0 of the wire are bent to act as stops against the rail (1, as shown, though a rod j may be employed for the same purpose and to place the separators in operative position.

Figs 7 and 8 show a separator similar to that indicated in Figs. 1 and 2 made from a flat metal strip p having holes 9 at its rear ends to engage with a long pivotal wire 9' which is suitably secured to the rail (0 by pivot plates 9 which are passed between the rear arms of each separator or at the outer sides of such to hold them in the required position with relation to the yarn bobbins.

The portion 8 of each separator acts as a stop against the rail a when turned to 111 operatlve position.

Figs. 9 and 10 show a separator of the type shown in Figs. 7 and 8 in which the pivots t are struck out from the main body of the portion of the upper surface of the said rail which forms a stop, said separators being independently movable and adapted to be raised pivotally out of contactwith the said stop.

2. The combination with a pivoted supporting rail, of a series of projecting cover plates secured to the upper surface of the rail and having ho0k-shaped front ends, and a series of separators each comprising a ,Wire loop having pivots at its ends adapted to be sprung into engagement with the hook shaped ends of the cover plates to which it pertains and normally resting on one side portion of the upper surface of the said rail which forms a stop, said separators being independently movable and adapted to be raised pivotally'out of contact with the said stop.

In testimony'whereof I have hereunto set my hand in the presence of two witnesses.
